Richmondichthys Flank Scale

A large, long flank scale of Richmonichthys sweeti. Such scales would line the body, and are a typical trait of the Aspidorhynchidae.

Mycelites cf. enameloides

Thu, 21 May 2026 06:59:04 +0000

The tiny, tiny boring on this Echinorhinus australis bramble shark tooth demonstrates something rather exciting: the possibility of aquatic fungi in the Toolebuc Formation! Such borings are apparently very common on fish and shark teeth in the UK, so I'm not all too surprised to find them here, but it's still very exciting! Other possible candidates for the tracemaker include oomycetes (which are actually eukaryotes related to diatoms) and bacteria.

Rogerella sp. Ichnofossil on Peratobelus oxys Belemnite

The ichnofossil Rogerella, the boring trace of an Acrothoracican barnacle, on a Peratobelus oxys belemnite. This is the first arthropod I have from the formation, so I am mighty pleased!

Likely Pterosaur Bone

Mon, 24 Feb 2025 06:09:06 +0000

A fragmentary hollow bone found on a dig with the Kronosaurus Korner Museum. They said it was "something that flew"- so either a bird or a Pterosaur. Note the two belemnites just relaxing on the bone. ~5.5cm long. I'm very proud of this one!

Eutrephoceras hendersoni

A nautiloid from Julia Creek in the Toolebuc Formation. Rather complete specimen.

Tropaeum

Tue, 28 Jan 2025 06:42:17 +0000

An ammonite from the Toolebuc Formation. There are several species, including T. australis and T. jacki. I believe this to be T. australis.

Partial Toxoceratoides taylori

Tue, 28 Jan 2025 06:42:15 +0000

A Heteromorph ammonite. This species is currently unsure and under investigation.

Inoceramus sutherlandi

Tue, 28 Jan 2025 06:22:28 +0000

A partial shell from Inoceramus ?sutherlandi? (Unsure here), a large bivalve and one of the only two that could live on the rather anoxic sea floor of the Eromanga Sea. Rather common fossils.

Large Fish Vertebra

Tue, 28 Jan 2025 06:22:27 +0000

Vertebra from a large Osteichthyan (Bony Fish), possibly Cooyoo australis, Richmondichthys sweeti, Dugaldia emmilta, or Pachyrhizodus marathonensis, or a variety of others. Found in Fish Mash on Dig with Kronosaurus Korner Museum.

Turtle Phalange

Tue, 28 Jan 2025 06:22:24 +0000

A small (maybe proximal) phalange from a turtle, likely Notochelone costata. Big thanks to Shellseeker and Mike from North Queensland for helping with the ID. Found in Fish Mash on dig with Kronosaurus Korner Museum.
